A truncated cube composed by six regular octagons and eight equilateral triangles.

Polyhedron with fourteen faces: six regular octagons and eight equilateral triangles. It has thirty six edges and twenty-four vertices. It is a Archimedean solid as it is a convex uniform polyhedra composed of regular polygons meeting in identical vertices, excluding the five Platonic solids (which are composed of only one type of polygon) and excluding the prisms and antiprisms.

The surface area of a truncated cube with edge length a is given by the formula:

\text{Surface area}=2 \left(6+6 \sqrt{2} + \sqrt{3} \right) a^2

The volume of a truncated cube with edge length a is given by the formula:

\text{Volume}=\frac{21+14 \sqrt{2}}{3} a^3
